Spirodiclofen Application Scenarios & Real-World Cases
Case Study 1: Citrus Orchard (Valencia, CA, USA)
- Problem: High infestation of Tetranychus urticae (two-spotted mite), with resistance to abamectin.
- Solution: One application of Spirodiclofen 24 SC (230ml/ha) achieved a 96% reduction in mite population after 14 days, while maintaining citrus fruit residue <0.05 mg/kg (below US/EU MRLs).

FAQ: Expert FAQ on Spirodiclofen Specifications & Practices
-
Q1: What is the exact material composition of Spirodiclofen 24 SC?
A1: Spirodiclofen 24 SC comprises 24% spirodiclofen (C21H24Cl2O4, AI ≥98% purity), with proprietary dispersants and stabilizers. Non-ionic surfactants and low-toxicity carriers make up the remainder, as per FAO/WHO pesticide formulation standards.
-
Q2: Which formulations are available?
A2: Mainstream: 24% SC (Suspension Concentrate), with WG (Water-dispersible Granule) and EC (Emulsifiable Concentrate) variants for region-specific needs.
-
Q3: What detection standards and quality certifications does your product meet?
A3: Each lot passes ISO 9001:2015, FAO/WHO formulation tolerances, and is HPLC, LC-MS tested for AI and impurities. Full compliance to US EPA, EU, and China pesticide MRLs.
Third-party testing via SGS and Bureau Veritas is available for all exports.
-
Q4: What is the optimal application dosage for field crops?
A4: 180–240 mL/ha (typically in 500–1,000L water/ha); repeat interval 21–28 days; observe local PHI and preharvest intervals as per country regulations.
-
Q5: Which installation standards and packaging types are offered?
A5: Factory-fitted in certified HDPE bottles (100ml, 500ml, 1L) & metal drums (5L, 20L, 200L), per UN/DOT and Q/SH001 national standards. All labels/closures are tamper-evident and GHS-compliant.
-
Q6: How does spirodiklofen compare to abamectin or fenpyroximate on resistance management?
A6: Unlike abamectin or pyrazole acaricides, spirodiclofen disrupts lipid biosynthesis (unique mode of action, IRAC Group 23), helping delay resistance and ensuring longer rotational value in IPM programs.
-
Q7: What is the expected shelf life and recommended storage conditions?
A7: 18–24 months unopened, 6 months after opening (5–30°C, dark, dry). Replace cap tightly; do not freeze or expose to direct sun.
